  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is an external perspective view of a musical instrument according to the first embodiment of the present invention. The musical instrument of the present embodiment is configured as, for example, an upright piano type keyboard instrument having a keyboard composed of a plurality of keys that are performance operators. FIG. 2 is a right side view of the musical instrument. Hereinafter, the player side is referred to as “front” and the right side in front of the instrument is referred to as “right” when viewed from this instrument.

  This musical instrument has a musical instrument main body 10, a keyboard KB, and a lid 20 for the keyboard KB. Further, on the back side of the keyboard KB, the musical instrument main body 10 is formed with a rising portion 10a rising upward. In the lower half of the musical instrument main body 10, main sound generators 11 and 11 in which the main speakers 12 are housed are provided on both the left and right sides, respectively (small speckle portions shown in the figure). A portion of the musical instrument main body 10 that extends forward from a substantially middle portion in the vertical direction is a portion on which the keyboard KB is placed on the shelf board, and a tip portion of the portion is a mouth bar portion 13. Time signatures 14 are provided on the left and right sides of the keyboard KB (see FIG. 2).

  On the front surface 10aa of the rising portion 10a, in order from the bottom, a name plate 15 (15L, 15R), various operation element groups 16 (16L, 16M, 16R) each consisting of a large number of operation elements, and a sub-acoustic generator 17 (17L, 17R) is disposed. The sub-sound generator 17 accommodates a monitor speaker 17a. Of the various operator groups 16, the various operator groups 16M are operators that do not require much operation during performance. On the other hand, the various operation element groups 16L and 16R are a set of operation elements that are relatively required to perform operations during performance, such as a musical tone parameter setting operation element and a registration switch.

  A name plate 18 is erected on the front portion of the upper surface 10ab of the rising portion 10a. On the name plates 15 and 18, logos such as brand names, model names, and series names are engraved. In particular, the name plate 15 has a thickness and projects forward from the front surface 10aa of the rising portion 10a.

  The lid 20 is composed of an upper plate 21 and a lid front member 22 attached to the tip 21 a of the upper plate 21. A rotating shaft 19 is provided along the left-right direction at the front of the rising portion 10a. The rotation shaft 19 is configured to have a hinge (not shown), but the length of the hinge in the left-right direction may be a single length over the entire length of the lid 20 or a relatively short hinge. The rotating shaft 19 may be configured by providing a plurality of portions. The top plate 21 is configured such that a tip end portion 21a thereof can be pivoted in the vertical direction about the pivot shaft 19, whereby the lid body 20 can be opened and closed from a closed state to an open state by manual operation. ing. The musical instrument is provided with a damper mechanism (not shown) so that the lid 20 is closed slowly.

  In the open state, the lid 20 is positioned by the upper plate 21 coming into contact with the name plate 15 as shown by a solid line in FIG. 2, and tilted obliquely rearward in the vicinity of the front surface 10aa of the rising portion 10a. Stand up in state. The name plate 15 has elasticity and absorbs the impact of contact with the upper plate 21 when the lid is opened. In addition, it is desirable to perform processing (for example, coarse processing) on the surface of the upper plate 21 so that discoloration or the like due to secular change is not conspicuous on the contact portion with the name plate 15. On the other hand, when the lid 20 is in the closed state, the upper plate 21 covers the keyboard KB from above, as indicated by a virtual line in FIG.

  FIG. 3 is a partial side view of the vicinity of the tip 21a of the upper plate 21 of the lid 20 in the closed state.

  The lid front member 22 includes an attachment portion 22a, a blindfold portion 22b, and a mouth bar contact portion 22c, and is integrally formed of a material such as aluminum by extrusion molding or the like. The lid front member 22 is fixed to the upper plate 21 by attaching the mounting portion 22a to the distal end portion 21a of the upper plate 21 with the screw 23 being obliquely upward and rearward in FIG. The

  In the closed state, as shown in the figure, the blindfolded portion 22b hangs diagonally forward and downward from the rear half of the mounting portion 22a, and from the lower end of the suspended blindfolded portion 22b, the mouth stick portion contact portion 22c. Extends forward. The blindfold portion 22b and the mouth stick portion contact portion 22c are collectively referred to as a “keyboard hidden portion C1”. A cushioning material 22d such as rubber fitted in a groove provided over the entire width of the front lid member 22 is provided below the mouth bar contact portion 22c. The keyboard concealment portion C1 has a substantially L shape when viewed from the side. In the closed state, the mouth bar portion abutting portion 22c abuts on the mouth bar portion 13 to perform the positioning function of the lid 20, and the blindfold 22b blinds the keyboard KB from the front. The front lid member 22 is formed in a substantially U-shaped bag shape in a side view when the front side is closed, and the surface facing the blindfold 22b of the attachment portion 22a has a finger 24 when performing a lid opening operation. It functions as a finger hanging portion 22aa for hanging.

  On the other hand, in the open lid state, as shown in FIG. 2, the lid front member 22 supports the lower end 25a of the musical score 25 from below. More specifically, the blindfold 22b directly supports the lower end 25a of the musical score 25, as indicated by phantom lines in FIG. The name plate 18 and the front surface 10aa of the rising portion 10a support the back surface 25b of the musical score 25 from the rear. In FIG. 2, the music score 25 is shown in a state of no deflection when viewed from the side, but in reality, a slight flexure may occur, so that the back surface 25 b of the music score 25 is composed of the name plate 18 and the rising portion 10 a. Are supported by either or both of the front surfaces 10aa.

  As described above, in the opened state, the blindfold 22b and the name plate 18 and / or the front surface 10aa of the rising portion 10a cooperate to perform the music stand function. Furthermore, in the musical score holding state in the open lid state, the mouth bar portion contact portion 22c of the lid front member 22 serves as a stopper function that prevents the lower end 25a of the musical score 25 from dropping forward. The blindfold 22b, the mouth stick contact portion 22c, and the name plate 18 each have original functions other than the music stand function, such as a keyboard blindfold function, a positioning function when the cover is closed, and a logo display function. The front surface 10aa of the portion 10a is a portion normally provided in the upright piano type musical instrument. That is, the rising portion 10a is necessary to accommodate an action mechanism in an upright piano type acoustic musical instrument and a circuit component, an acoustic component, and the like in an electronic musical instrument, and thus has a front surface 10aa. Therefore, the music stand function can be realized without providing a dedicated mechanism for the music stand, and the configuration can be simplified.

  In particular, since the name plate 18 is arranged at a low position so as to be hidden by the music score 25 in order to make the name plate 18 perform the music stand function, the name plate is placed at a position higher than the upper end position of the music score 25. Compared with the case of providing, the height of the musical instrument including the name plate 18 can be kept low.

  The various operator groups 16 (mainly the musical tone parameter setting operator groups) are generally arranged behind the keyboard, but in the present embodiment, the various operator groups 16 are arranged on the front surface 10aa. As a result, it is not necessary to provide it behind the keyboard KB. Therefore, when the lid body 20 is configured to cover the visible portion (the total length of about 8 to 10 mm) of the entire length of the keyboard KB in the front-rear direction, the length of the lid body 20 in the front-rear direction can be set short. For example, the total length of the lid 20 is about 10 to 18 mm. When such a short lid 20 is erected, the upper end position of the lid 20 may be low, so that the position of the upper surface 10ab of the rising portion 10a can be set low. This also makes it easy to keep the instrument height low.

  Each of the various operation element groups 16 and the sub sound generation unit 17 is located above the upper end position of the lid 20 in the opened state. In addition, among the various operation element groups 16, the various operation element groups 16L and 16R and the sub-sound generation parts 17L and 17R are located on the left side of the part of the front surface 10aa of the rising part 10a that supports the back surface 25a of the musical score 25 from the rear. And on the right side (see FIG. 1). Therefore, when the musical score 25 is placed when the lid is opened, and further when the musical score is placed on the musical score, the generation of sound from the sub-acoustic generator 17 and the operation of the various operator groups 16L and 16R are hindered. Never give. When the musical score 25 is not placed when the lid is opened, there is no hindrance to the operation of the various operator groups 16M.

  According to the present embodiment, the blindfold 22b serves both as a keyboard blindfold function and a support function for the lower end 25a of the music score 25, and the name plate 18 serves as a logo display function and a support function for the back surface 25b of the music score 25. Since the front surface 10aa of the rising portion 10a provided functions to support the back surface 25b of the music score 25, a music stand function can be realized with a simple configuration. In addition, since the mouth bar contact portion 22c serves both as a positioning function of the lid 20 when the lid is closed and a stopper function of the music score 25 when the music score 25 is placed, a music score falling prevention function is realized with a simple configuration. be able to.

  In addition, since the various operator groups 16L and 16R and the sub-sound generators 17L and 17R are arranged so as to be exposed without being hidden by the lid 20 or the music score 25 even when the music score 25 is placed in the opened state, Generation or musical sound parameter setting operation is not hindered.

  Moreover, since the attachment portion 22a of the lid front member 22 functions as a finger hook portion 22aa at the time of the lid opening operation, the lid front member 22 eventually has three functions of a keyboard blindfold function, a music score lower end support function, and a finger hook function. Doubles as Therefore, it is possible to realize a finger hooking function for opening operation without complicating the configuration.

  As indicated by phantom lines in FIG. 2, a recess 10d is provided in the lower portion of the front surface 10aa of the rising portion 10a so that the upper plate 21 of the lid 20 is just accommodated in the recess 10d when the lid is opened. It may be configured. In this way, when the musical score 25 is placed on the lid front member 22, the rear surface 25b of the musical score 25 can be supported by the entire front surface 10aa, and the posture of the musical score 25 is further stabilized.

(Second Embodiment)
FIG. 4 is a right side view of the musical instrument according to the second embodiment of the present invention. FIG. 5 is a front view showing the upper half of the musical instrument in the opened state. The musical instrument of the present embodiment is configured as an upright piano type keyboard musical instrument, and the configuration of the lid is greatly different from that of the first embodiment, and the basic configuration of the musical instrument main body is the same. This musical instrument has a musical instrument main body 110, a keyboard KB, and a lid 120 for the keyboard KB.

  The configuration of the lower half of the musical instrument main body 110 is the same as that of the musical instrument main body 10 in the first embodiment although not shown. The configuration of the rising portion 110a of the musical instrument main body 110 is the same as that of the rising portion 10a in the first embodiment, and the name plates 15 and 18, various operation element groups 16, and the sub sound generating portion 17 are provided in the same manner. The length of the keyboard KB in the front-rear direction is longer than that of the first embodiment. A lid holding member 9 is provided on both the left and right sides of the keyboard KB, and a beat tree 114 is provided in front of the lid holding member 9.

  The various operator groups 16 may be provided behind the keyboard KB between the two lid holding members 9. At the same time, the main sound generators 11 and 11 may be abolished, and the monitor speaker 17a may be configured to be large and used as the main sound generator instead of the main sound generators 11 and 11. .

  The lid 120 includes a first upper plate 121, a second upper plate 122, a lid front member 123 attached to the distal end portion of the second upper plate 122, and an attachment plate 126. The first upper plate 121 and the second upper plate 122 are connected to each other at the connecting portion CON so as to be able to bend and stretch, that is, turnable from the extended state to the folded state. The first upper plate 121 is configured to be rotatable in the vertical direction about the rotation shaft 19.

  FIG. 6A is a right side view of the connecting portion CON when the lid 120 is folded. FIG.6 (b) is the perspective view which looked at the cover body 120 in the folding state from diagonally right upper back. As shown in FIG. 5, two connecting parts CON (CON (L), CON (R)) are provided at symmetrical positions.

  As shown in FIGS. 6A and 6B, the connection side end 121a of the first upper plate 121 and the connection side end 122a of the second upper plate 122 are parallel hinges H1 (H1L, H1R). It is pivotally connected. That is, the parallel hinge H1 includes a shaft portion 128, a first hinge piece 129, and a second hinge piece 130, and the first hinge piece 129 is fixed to the connection side end portion 121a of the first upper plate 121 with a screw 124. At the same time, the second hinge piece 130 is fixed to the connection side end portion 122 a of the second upper plate 122 with a screw 125. Thereby, the cover body 120 has a crank structure in which the connecting side end portion 121a of the first upper plate 121 is higher than the connecting side end portion 122a of the second upper plate 122 in the folded state, and a stepped portion is generated.

  When the lid 120 is in the open state, as shown by a solid line in FIG. 4, the first upper plate 121 on the front side and the second upper plate 122 on the rear side are folded, and the second upper plate 122 is positioned by coming into contact with the name plate 15 and stands up in a state of being inclined obliquely rearward in the vicinity of the front surface 110aa of the rising portion 110a. On the other hand, in the closed state, as shown by the phantom line in FIG. 4, the lid 120 is in the extended state, and the second upper plate 122 is held by the left and right lid holding members 9. In this closed state, the first and second upper plates 121 and 122 cover the keyboard KB from above, and the lid front member 123 abuts the mouth bar portion 113 to perform the positioning function of the lid 120 and the keyboard KB. Blindfold from the front.

  Further, as shown in FIG. 6A, a supplementary plate 126 is fixed to the surface of the second upper plate 122 that faces the keyboard KB when the lid is closed. The attachment plate 126 is provided so as to protrude from the connection side end portion 122a so as to overlap the first upper plate 121 in the closed state. The accessory plate 126 serves to restrict the second upper plate 122 from rotating further in the counterclockwise direction in FIG. 4 than the first upper plate 121 in the connecting portion CON (so-called reverse folding). Fulfill.

  On the other hand, in the opened state, as shown in FIGS. 4 and 6A, the second hinge piece 130 of the parallel hinge H1 supports the lower end 25a of the musical score 25 from below. That is, the connection side end portion 122 a of the second upper plate 122 substantially supports the lower end 25 a of the musical score 25. Similarly to the first embodiment, considering the case where the music score 25 is bent, the name plate 18 and the front surface 110aa of the rising portion 110a support the back surface 25b of the music score 25 from the rear.

  Further, in the musical score holding state in the opened state, the connecting side end portion 121a of the first upper plate 121 to the shaft portion 128 of the parallel hinge H1 serve as a stopper function that prevents the lower end 25a of the musical score 25 from dropping forward. In this state, the accessory plate 126 also serves as a stopper that prevents the lower end 25a of the musical score 25 from dropping backward.

  In addition, as shown in FIG. 5, the parallel hinge H2 (H2L, H2R) and the movable plate 127 (127L) are positioned between the connecting parts CON (L) and CON (R) at positions that can face the musical score 25 placed. 127R). As shown in FIG. 6B, the parallel hinge H2R includes a shaft portion 131 and first and second hinge pieces 132 and 133. The movable plate 127 </ b> R is configured as a separate member from the first upper plate 121. The first hinge piece 132 is fixed to the movable plate 127R and the second hinge piece 133 is fixed to the second upper plate 122, so that the movable plate 127R is independent of the first upper plate 121 and the second upper plate 122. Is freely rotatable. Further, the parallel hinge H2R is configured to exhibit an appropriate frictional force as long as the movable plate 127R can be manually rotated. The configurations of the parallel hinge H2L and the movable plate 127L are the same as the parallel hinge H2R and the movable plate 127R.

  In the musical score holding state in the opened state, when the movable plate 127 is rotated backward and the musical score 25 is pressed from the front, the movable plate 127 can fulfill the function of holding the musical score by the frictional force of the parallel hinge H2. On the other hand, during the closing operation, that is, when the musical score 25 is removed and the second upper plate 122 is rotated in a direction extending to the first upper plate 121, the second upper plate 122 is movable. Since the plate 127 is automatically driven in the same direction, there is no need to perform the operation of returning the movable plate 127 to be parallel to the first upper plate 121. Thereby, the complexity of the lid closing work caused by the movable plate 127 is avoided.

  As shown in FIG. 5, each of the various operator groups 16 and the sub sound generation unit 17 are located above the upper end position of the lid 120 in the opened state (in this embodiment, the upper end position of the attachment plate 126). . In addition, the various operating element groups 16L and 16R and the sub-sound generation units 17L and 17R are arranged so as to be exposed without being hidden by the lid 120 or the music score 25 even when the music score 25 is placed in an open state. This is the same as in the first embodiment.

  According to the present embodiment, the connecting portion CON performs the support function of the lower end 25a of the music score 25, and the name plate 18 serves as a logo display function and the support function of the back surface 25b of the music score 25, and is normally provided. Since the front surface 110aa of 110a also functions to support the back surface 25b of the music score 25, the configuration is simpler than when a dedicated mechanism for the music score is separately provided, and the first feature relates to realizing the music score function with a simple configuration. The same effects as in the embodiment can be obtained.

  Further, the connection side end 121a of the first upper plate 121 having a lid function of the keyboard KB and the accessory plate 126 having a reverse folding restricting function of the second upper plate 122 are stoppers in the front-rear direction of the lower end 25a of the musical score 25. Since the function is fulfilled, it is possible to realize the music dropout prevention function without complicating the configuration.

  In addition, the movable plate 127 can serve as a music score presser. In addition, since the pivot shaft of the movable plate 127 is located at a position along the connecting portion CON, the configuration is simple, the protrusion is small, and it is less likely to be caught when turning a musical score. Furthermore, since the movable plate 127 is hidden under the first upper plate 121 and the second upper plate 122 when the lid is closed, it looks good and is not easily damaged.

  Moreover, since the lid 120 is in a folded state when the lid is opened, the height of the lid 120 is low, and it is easy to place the musical score 25 at a low and easy-to-see position. That is, for example, when the various operating element groups are arranged not behind the position shown in FIG. 4 but behind the keyboard KB, or when the length of the keyboard KB is relatively long, the rising portion 110a (especially the rotating shaft 19). ) To the tip position of the keyboard KB, the position of the connecting portion CON that holds the musical score 25 can be set low in the opened state, so that the musical score 25 can be relatively lowered in position. it can. Therefore, if the distance from the rotating shaft 19 to the tip of the keyboard KB is short, the musical score position can be lowered accordingly.

  Further, the above arrangement of the various operation element groups 16L and 16R and the sub-sound generation units 17L and 17R has the same effect as that of the first embodiment with respect to the fact that the generation of sound or the musical sound parameter setting operation is not hindered. Can play.

  In the first and second embodiments, each of the various operating element groups 16L and 16R and the sub-acoustic generators 17L and 17R are provided in two symmetrical positions, but may be provided only in one of them. .

  In the first and second embodiments, the name plate 18 and the front surfaces 10aa and 110aa of the rising portions cooperate to support the back surface 25b of the music score 25 from the rear. From the viewpoint of realizing the function with a simple configuration, it is not limited to this. For example, the arrangement of the name plate 18 so that the back surface 25b of the musical score 25 is always supported only by the name plate 18 or only by the front surface of the rising portion. In addition, the positional relationship with the front surface of the rising portion may be set. In addition, what supports the back surface 25b of the musical score 25 from back is not limited to the name plate 18, For example, the protrusion-shaped member thru | or part arrange | positioned along the left-right direction may be sufficient.

  It should be noted that at least a part of the name plate 15 may be made of a magnet, and a plate made of a magnetic material such as iron may be attached to a portion of the lid 20 or 120 that contacts the name plate 15. In this way, since the name plate 15 sucks the lids 20 and 120 in the opened state, the lids 20 and 120 are closed even when the weight of the musical score 25 to be placed is large. The lid movement is hard to be induced. Accordingly, even when the front surfaces 10aa and 110aa of the rising portions 10a and 110a are further steeply inclined, it is easy to stably maintain the open state of the lid bodies 20 and 120.

  In the first and second embodiments, the configuration in which the various operation element groups 16 are arranged in the rising portions 10a and 110a is exemplified. However, the musical score is placed on the upper portion of the lid in the opened state. In view of the above, the various operation element groups 16 are arranged on the back surface (lower surface) when the lid 20 is closed (in the second embodiment, the back surface when the first upper plate 121 of the lid 120 is closed). By arranging, the following further effects can be obtained.

  For example, by disposing the various operation element groups 16 and the liquid crystal display unit on the back surface (lower surface) when the lid 20 is closed, there is no problem in manipulator operation and display even when the musical score is placed. Since the various operation element groups 16 are closer to the player as compared with the case where the various operation element groups 16 are disposed in the rising portion 10a, the operation and visual recognition are facilitated. In addition, since it is not necessary to arrange the various operation element groups 16 in the rising portion 10a, the height of the rising portion 10a can be lowered when applied to an electronic keyboard instrument that does not require strings, and the feeling of pressure during performance can be reduced. As the number decreases, the player's face can be seen from behind the instrument.
